Still hurt over the way things ended with Lucas, she begins relations with her neighbor, Felix Taggaro, who becomes a "friend with benefits." Later, things become strained between Brooke and Mouth when he tells her that he is in love with her, despite the fact that Brooke thinks of him as a "little brother." Meanwhile, she begins dating Felix after he promises to not break her heart as Lucas did.
During this time, Brooke decides to run for Tree Hill's student body president against students who are much more studious, hard-working, and experienced.
She takes a liking to Lucas Scott when he joins the school's basketball team, attempting to pursue him in her usual, sexual advances.
Lucas, however, is only interested in her best friend, Peyton Sawyer, and constantly turns down Brooke's advances.
Along with Peyton, she becomes a key player in the series' central love triangle involving Lucas Scott.
In later seasons, however, her character arc shifts its attention to her career as a fashion designer at Clothes Over Bros, as well as her romance and eventual marriage to Julian Baker, with whom she would have twin sons, Davis and Jude Baker.
After ending things with Felix, sexual tension begins to arise between Brooke and Lucas; however, after finding letters Lucas wrote to Peyton, Brooke believes that Lucas is still pining over Peyton and ultimately decides to just be friends with him.
During this time, Brooke experiences a pregnancy scare, eventually learning that her results were actually negative; however, in the heat of an argument with Lucas, she lies to him and tells him that she is pregnant with his child.
When she comes clean about the truth, Brooke explains that she wanted to punish Lucas for cheating on her with Peyton.
Toward the middle of the season, Brooke learns that her father was able to secure a new job and that her family is moving to California as a result.
However, she is thrilled when she finds out that Lucas has convinced Brooke's parents to let her live with Karen until the summer, where she will be staying in Lucas' room as he is living with Dan.
She shares a close bond with first-love Lucas Scott, and has also formed many close friendships.
